摘要

摘要: 将炸药的水下爆炸能量测试方法与冲击波感度测试方法（小隔板法）相结合，研究了一种测试炸药冲击波感度的方法水下卡片间隙试验法，并用该方法得到了6种炸药冲击波感度的相对排序（从高到低）：炸药泰安、黑索金、8701、钝化黑索金、梯恩梯、膨化硝酸铵的冲击波感度依次降低，该试验结果与文献值、传统隔板试验结果一致，表明水下卡片间隙试验法的测试结果是可信的，水下卡片间隙试验法用于测定炸药冲击波感度是可行的，在一定程度上可代替传统的隔板试验法，此方法还可用于研究炸药装药密度对其冲击波感度的影响。

Abstract: An underwater card gap test method was proposed to measure shock sensitivity of explosives by combining the underwater explosion method and the small card gap test. The shock sensitivity of six explosives, which included PETN, RDX, 8701, Desensitized RDX, TNT, expanded ammonium nitrate explosive, was measured by the proposed underwater card gap test method.The experimental results show that the shock sensitivity of six explosives including PETN, RDX, 8701, Desensitized RDX, TNT and expanded ammonium nitrate get down successively. The results by the underwater card gap test method were compared with the results by the traditional gap test and the results from literatures. Comparison indicates that the experimental results are believable. Furthermore, effect of charge density on shock sensitivity of explosives was investigated by the underwater card gap test method.
